LUBRQCATOR.

Specification of Letters Patent.

Patented Feb. 15,

Appnation mea August 15, 1914. serial no. asaezaf To all whom t may concern.'

Be it known that 1, ROBERT lVooD, a subject of the King of Great Britain and Iref land, residing at 435 East Fourth street, Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to torce feed lubricators, and one of the objects of the invention is to provide a lubricator of this type which is substantially without any valves or valve mechanism to control the oscillation of a portion of lubricant or its discharge from the apparatus.

The further object of the invention is to provide actuating means for such a lubricator, including -a plurality of selectively actuahle parts whereby the apparatus may be caused toA feed more or less lubricant in a `given time.

Other objects and aims of the invention, more or'less broad than those stated above,

together with the advantages inherent. will be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations, arrangement of parts and applications ot' purpose constitutingr the invention; and the scope of protection contemplated will appear from the claims.. A

ln the accompanyingir drawings, which are to be taken as apart of this specification, and in which I have shown a merely preferred form ot embodiment oi the invention, Figure 1 is a view in vertical section, with parts' in elevation, showing' the apparatus embodying the invention, and Fig. 2 is a detail sectional view with parts in elevation showingy the multiple actuating device.

I'leferringg, to the numerals on the draw ings there appears at 4 a reservoir Which may be provided with the usual strainer 5 and closure cap G and vent 7.

In the bottom of the reservoir there is an outlet 8 and another outlet 9. These outlets 8 and 9 open into a cylindrical space formed beneath the reservoir 4. in the body7 21, andin this cylindrical space is' adapted to reciprocate a plunger 10. This plunger 10 has a head 11 and a lubricating groove 12, with which lubricating groove the outlet 9 is always in communication, and beyond the head 11 the plunger carries a reduced portion 1l. The plunger 10 is moved in one direction by means of the coiled spring 15, that bears between the head 11 and the end wall 16 of the cylindrical space, while it is moved in the other direction by means of the engagement with its end portion 17 of a cam 18 mounted on a shaft 19, which shaft is caused t0 rotate or oscillate in a manner hereinafter to be described. The reduced portion 14 of the plunger'enters a correspondingr cylindrical space 20 formed in the body 21, and there are also provided passages and 24. communicating respectively with the cylindrical space 13 and the Cylindrical space 20. There is also a passage that leads out from the end oi the cylinder space 20. The plunger 10 is shown in Fig. 1 at its limit of movement in one direction, in which position the outlet 8 from the reservoir is in communication with the cylindrical space 13. lt will be evident that if the plunger be now moved toward the right in Fig. 1 against the force of the spring 15, the oil within the space 18 will escape by way ot' the passage rlfhis passage 22 is controlled at its upper end by means of a regulator which is in the form of a rod 26. This rod 26 is slidable in a plug 27, and this plug' 2T is screw-threaded in the housing 31. The end of the rod is provided 'vvith a conical member 2S, which controls the upper end of the passage 22, and the head 28 is driven into closingl position by means of a coiled springr which bears between the head 28 and the end wall of the bore 30 of the plug. As the plug is screwed up more orless the tension of the coiled spring 29 will be adjusted accordingly.

31 indicates a jam-nut which may be used in cooperation with the plug. The hollow part of the plug is provided with apen tures 32 in its side walls, from which may escape any oil that finds its way 'from the passage 22 into the space 30. and from these apertures 32 the oil nds its way through a perforated plug Se, through a sight-glaes that shown in and by Way' of the passage 2l into the space Q0, whence it is driven by the niovenient of the reduced part. H through the passage 25 and past the spring-pressed regie lator 3G into a space 3T torined in a thiinble 23S thaty is screw-tl'ireaded into the bod)Y 2l. The regulatorcomprises a rod and a cone head controllingA the passage and a coiled spring 39 which bears between the cone head and the aperturcd outer end ol the thirnble. the said rod extending within the apertured end of the thiinble. and being lon; jitndinalljvY reduced or grooved to permit of the passage ol oil from the space 3T past it and out of the thiinble. "lilith each reciprocatiou of the plunger l and the reduced portion ll toward the right in Fig. l, there will be a portion ol:t lubricant sent up through the passage 22, and siimiltaneousl)v the portion ot' lubricant previously left in the cylindrical space 2O will be forced out through the passage rlhe quantity of oil delivered at each stroke vvill. of course. depend upon the length ot' the stroke in connection with the cross-sectional area oi'' the plunger and reduced part 'll respectively. n

The reciprocation of the plunger l0 may be accomplished by means of 'the apparatusshown. That is to say a .shaft lil may be mounted to rock or rotate'in soine fixed relation to the apparatus, and this shaft may carry a cam 18., having: one or more bulges. Obvious-lv if this shaft rocks or rotates the hulges will cause the movement of the plunger against the force of the spring and with a cani sul stantialljvY like Fig. l.. an oscillation of the shaft through an arc of ninetyY degrees would accomplish the proper'reciprocation of the plunger.

In order that the device ma;Y be utilized with what is shown as a ratchet driver. or with a. pulley drive., or with. an oscillating drive, selectively at ivill` I mount upon the shaft- 19 a fork 40, and between the 'bifurcations I provide a pulley 4l mounted upon the shaft 19 and having' a groove 'for the accommodation of a belt l2. {ln either side of the lgroove the porii'ihery oliv the Wheel is .provided with alined ratchet teeth -l-l, and in the upper end o the fork l() there is mounted a ratchet 45 which under certain circumstances is intended to cooperate with the ratchet teeth i4. I also provide a pin Nlll. which passes through an aperture in one lea` of the fork. thence through an aperture 51.7 that extends through the -wheel. and thence into screnthreaded engagement with the other leg' ot the fork as indicated at i8. The fork nia)Y be moved about its pivot,

'which is the shaft l0` b v means of a con nectilreT rod 49 that mav comprise or be actua-ted from some moving part ota machine. If the pin #lo be in place, however,

as shown in Fie'. Q, it is obvious that there can heno movement of the wheel l-l. relativel),7 to tl1eto1l{ il), so that an)v o.V illatiou of the fork l0 vvill result inerelv in oscilla tion oir' the shaft lJ and consequciuly of the cani 18. lf the. pin lll be not in place.y oscillation of the fork Yl-O will result in aulvancinfthe wheel l step-b vetep and rotation ol shaft 19, on account ot the engagement ot the ratchet with the teeth ivi. rlhc consequence will be a very inuch slower feed oi the lubricant. l a verjv7 rai feed is desired` the pin l? may be lett out and the wheel il driven b v means ofY the belt 4:2, at aufvv speed de' lnasniuch Vas many changes could be made in the above constriuion. and inanjv apparentl;V Widely diilerent embodiments of niv invention could be made Without dci'iartinfr from the scope thereof. it is intended that all. matter contained in the above description or shown in the acconnninyingr dravvii'es shall be interpreted as illustrative and not in a lil'i'iiting sense.

lt is also to be understood that the language used in the tollo'vvine' claims inA tended to cover all the ,eenm'ic and simi-ith.: features of the invention herein described and all statements of the scope ol' the invention which, as a matter of language, iniejht be said to fall therebetween claim:
